KIOXIA’s KumoScale Software Demonstrates 60x Storage Improvement Over Traditional Ceph Software

Simple Software Change on Same Hardware Drives Massive Block, Object and File Storage Improvement

SAN JOSE, Calif., October 8, 2020 – KIOXIA America, Inc. (formerly Toshiba Memory America, Inc.) today announced that, in recent benchmark performance tests, its KumoScale™ storage software based on NVM Express™ over Fabrics (NVMe-oF™) technology was able to improve performance when compared to Ceph™ software. Testing conducted in a networked environment that included the NVMe-oF specification and a TCP/IP transport showed that KumoScale software’s read performance is 12x faster than Ceph, and read latency is reduced by 60%. With similar loads, under the same testing conditions, write performance is 60x faster than Ceph while latency is reduced by 98%.

Summary of Benchmark Testing Results

  • Testing Environment: Test environment utilized industry standard TCP/IP transport, 100% random workloads, and triply replicated volumes for resilience in both cases.
  • Read Performance: KumoScale software read performance is 12x faster than Ceph software while reducing latency by 60% in the testing environment.
  • Write Performance: KumoScale software write performance is 60x faster than Ceph software while reducing latency by 98%.
  • Economic Impact:  KumoScale software supports 15x more clients per storage node than Ceph at a much lower latency in the testing environment.
     

“Measuring performance for a storage architecture based on the NVMe-oF specification is a complex task,” noted Joel Dedrick, vice president and general manager, networked storage software, KIOXIA America, Inc. “Storage dollars per IOPS and read latency are the new critical metrics for the cloud data center. Our recent test report highlights the raw performance of KumoScale software, and showcases the economic benefits that this new level of performance can deliver to data center users.”

Definition of capacity - KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1Gbit = 230 bits = 1,073,741,824 bits, 1GB = 230 bytes = 1,073,741,824 bytes and 1TB = 240 bytes = 1,099,511,627,776 bytes and therefore shows less storage capacity. Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, and/or pre-installed software applications, or media content. Actual formatted capacity may vary.
